Ok so since your queen does not have any workers yet and is not semi-claustraul, she actually doesn’t even need a foraging area and doesn’t need to be fed. My Lasius alienus queens had dried up test tubes, so I connected another test tube setup to their current ones. Even if they don’t move over to the new test tube, I find that the humidity from the new test tube setup is enough to drift over to the queens in the old setup and provide them with moisture. What you do is you place the two test tubes so that the openings of the tubes are an extremely small distance from each other. Then you wrap it up with tape and poke holes through the tape so air can get in.
